摘　　要：基于束晕-混沌的非线性控制策略,研究了均匀聚焦磁场通道中束晕-混沌的sinc函数控制方法,并给出了具体的实施方案.采用庞加莱截面技术对束核包络振荡及其单粒子运动轨迹进行了数值模拟.结果表明,运用此种方法可以有效地消除束晕及再生现象,达到对束晕-混沌的有效控制.Based on nonlinear control strategies of halo-chaos, a control method with sinc function is studied for controlling beam halo-chaos in the uniform-focusing channel and the practical implementation is performed. The beam envelope oscillations and the orbits of single-particle are simulated by using the Poincar6 mapping technique. The results show that the method is very effective for eliminating and regenerating beam halo-chaos.
